Labyrinth Seal 의 누설 특성 실험
An Experimental Study on the Leakage Characteristics of a Labyrinth Seal
초록
An experimental investigation on the leakage characteristics of a labyrinth seal, high-low seal, is studied. Pressure distribution and leakage flow rate are measured along with the shaft speed and the pressure difference between the entrance and the exit. Pressure distribution vanes almost linearly along the seal and the leakage flow rate increases as the increase of the pressure difference. Furthermore, it is found that both the shaft speed and the shaft vibration have no influence on the leakage of the labyrinth seal.
